Title: Improvements in or relating to machines for separating the yolk from the albumen of eggs
IPC: A47J43/14
Filed: 1939-03-07
Abstract: 526,245. Separating contents of eggs. KEENOK CO.. Ltd., and WALL, W. H. March 7,1939, No. 7422. [Class 28 (ii)] In a machine for separating the albumen from the yolks of eggs, of the type comprising a series of cups arranged in line along an endless conveyer, the cups are provided with perforations to permit albumen to drain through while retaining the yolk ; means are also provided for shaking and tilting the cups, and for wiping their under surfaces to remove adhering albumen. The endless conveyer 12 comprises two chains spaced apart and running over pairs of sprocket wheels 16, 18 mounted at opposite ends of the frame 10. The cups 20 are detachably carried in annular holders 22, Fig. 5, each having two pivot pins 24 journalled in the links of the chains. An arm 26 depending from one side of the holder carries a roller 28 adapted to engage cams for tilting and oscillating the cup during its travel. Each cup 20 is hemispherical, and has in its front side a dumb-bell shaped slot 44, 46, for the drainage of the albumen. The rollers 28 run on upper and lower cam tracks 50, 52, which are of wave form at parts 56, 62, 66, so as to oscillate or shake the cups and tilt them to permit the albumen to flow through the slots 44, 46. The upper cam track 50 has at the front end a downwardly-curved smooth portion 104 which is spaced from a curved portion 106 of the lower track to form a gap, whereby the cups are given a jerk when passing from one track to the other. The gap may, when desired, be closed by a removable curved member 108. The albumen is received in. trays 110, 112. The cups are tilted at the other end of the conveyer to pour the yolks on to a tray 114. Albumen adhering to the under surface of the cups is wiped off by means of a wire 74 stretched in a holder 80, which is oscillated transversely by means of a disc crank 82, connecting-rod 84, a bell-crank lever and links. In a modification, each cup has a wiping wire, which is carried by the conveyer and acts by the relative movement due to tilting of the cups. The machine may be combined with an egg-cracking machine of the 'kind described in Specification 510,794.

Patent GB-1087813-A (GB)
Title: Improvements in and relating to harvesters for root crops
IPC: A01D19/00
Filed: 1964-02-22
Abstract: In a method of harvesting potatoes a length of netting is laid adjacent to the row of crop to be dug, the netting having a flexible wire along its longitudinal edge adjacent to the row so as to be engageable within a circumferential groove in a driven wheel carried by, and projecting laterally from, a tractor which tows and drives a spinner to eject potatoes from the ground on to the netting.  The netting is held against the wheel, where it passes thereover, by an endless band entrained around pulleys to follow an arcuate path adjacent to the circumference of the wheel. The wheel and the spinner are both mounted on the tractor by linkage which enables them to be swung over to the opposite side of the tractor for the next run thereof.  The spinner, or several spinners, may be arranged to harvest several rows at a time.  When the netting is full, it is bodily removed by attachment to a tractor at each end.

Title: Improvements relating to coin-operated devices
Inventor: SMITH CHARLES
IPC: G07F17/24
Filed: 1959-03-05
Abstract: 864,501. Parking meters. BLOCTUBE CONTROLS Ltd. Dec. 16, 1959 [March 5, 1959], No. 7639/59. Class 27 A coin-operated time-controlled device such as a parking meter has a pair of flags 9, 10 released in sequence to indicate the expiry of purchased time and of excess time as a finger 18 on the shaft 3 of the pointer 2 moves clear of overlapping flanges 14, 15 on the flags. The flags are duplicated at each end of their shafts 5, 6. When a coin is inserted in a coin slot member 30 as described in Specification 775,509, a link 32 and pawl arm 34 are drawn down and then drawn upwardly by a spring 35. A cam disc 40 carried by the pawl arm pushes up a link 42 and rotates the shaft 5 so that the flags 9 are retracted. Because of the interengaging flanges 14, 15, the flags 10 are also retracted and a spring 13 passed over and under the shafts 5, 6 is tensioned and the finger 18 engages over the flange 15 as the pointers 2 move to indicate the purchased time on the scales 1. As the pointers reach the central zero of the scales, the finger 18 clears the flange 14 so that the flag 9 springs into view and as the end of the excess time is reached the finger 18 clears the flange 15 to release the flag 10. A control segment on the shaft 3 engages a stop to halt a driving motor when the end of the excess time is reached.

Title: Improvements in electrical telegraph and like signalling systems
IPC: H03B19/03
Filed: 1929-03-08
Abstract: 312,904. Electrical Research Products, Inc., (Assignees of Burton, E. T.). June 2, 1928, [Convention date]. Addition to 312,338. Transmitting systems for code telegraphy.- Relates to a signal transmission system of the type described in the parent Specification wherein the signal waves are shaped for high-speed transmission over a line, e.g. a submarine cable, by transformers having high permeability and adapted to carry a continuously flowing biassing current. As shown in Fig. 1, a signal transmitter 10 transmits impulses through transformers 13, 14, 15 to the grid circuit of a valve amplifier 11. The transformer 13 repeats only the lowfrequency current components, the high-frequency components being repeated over transformers 14, 15 which are provided with biassing coils 21, 22 and cores having high permeability. The biassing coils are wound in opposition and the currents therein cause the saturated condition of the cores to be maintained until the signal currents through the primary coils 17, 18 reach a definite positive or negative value to produce a state of de-energization for the production of a current impulse in one or other of the secondary coils 19, 20. In this manner an impulse occurs in each secondary coil to produce a double impulse at each reversal of the signal current. The secondary coils are connected to the grid of the amplifier 11 through networks 27, 28, 29 wherein the secondary impulses may be adjusted in phase and amplitude and undesired high frequency voltages may be suppressed. The resistance 24 and condensers 25, 26 constitute a filter circuit which prevents entry of high frequency signal current to the amplifier through the transformer 13. The low and high frequency components are combined for amplification and transmission over the line 12 which is connected to the output of the amplifier 11 at a point between the plate battery 30 and battery 32. Fig. 2 shows the various stages for producing a final wave form C from the original signal current A. The biassing currents are represented by lines d and the point at which the signalling current becomes effective to overcome the biassing effect is shown by lines e, the point of saturation of the transformer cores being represented by the lines f. When the signal current passes through the range e, f impulses B<11> are produced which combined with the curve B<1> form the final wave shape C. Specification 258,614 is referred to.

Abstract: 149,313. Volmer, M. July 26, 1919, [Convention date]. Aspirating-apparatus, ejector.-In a multistage mercury vapour pump, for the first stage a pump is used in which the air to be exhausted is led by cooled walls to the vapour jet. The vapour issuing from a nozzle b induces air from a pipe h and the mixture of vapour and air issuing from the nozzle e induces more air through the cooled pipe g and discharges it into the diffuser d connected by a pipe i to the preparatory vacuum pump. The whole is surrounded by a cooling- jacket k. Several liquid seals m are arranged in the pipe l for returning the condensed mercury to the vaporizer a. In a modification, tubs n, o. are arranged in the vapour nozzle t and are of such shape that vapour issues at full pressure out of the tube o through the nozzle q and at successively diminished pressure between the tubes o, n and n, h.
